Luscious blackberries layered with super moist and fluffy sponge cake and served with a scoop of vanilla ice cream. This was our family’s go-to dessert for every special occasion when I was growing up.

I’m so excited to finally share it with my Sugar Geek family in honor of what would have been my Mother’s 74th birthday. I snagged this photo from my Dad’s photo album and I dare say as I hit my 40’s, I look more and more like her every day.

What is blackberry sponge cake?

Blackberry sponge cake is a recipe that my mom made a lot when I was growing up. I never saw her measure the blackberries, it really depended on how big the dish was she was baking in which was usually a glass dish.

Every summer my Dad would send us to the backyard with a big 50-gallon bucket and a ladder to pick blackberries. They would be thick and hanging from the bushes that grew wild in huge bunches, sweetened by the sun to perfection. My sisters and I would not come back into the house until the bucket was full and our hands were stained with purple juices. We probably ate just as many berries as we picked.

My Dad would then begin the canning and freezing process. Some of the berries would be transformed into thick blackberry syrup that he would ration out for only very special occasions. Some would be made into jam and some would be canned to use in the wintertime.

But we always saved a couple of quarts to make some fresh blackberry sponge cake. I watched my mom make this many times and after she passed away, my Dad would make it, and then when I was old enough, I also would make it.

This recipe is very near and dear to my heart and I hope you enjoy it with your family as much as I enjoyed it with mine and a little bit of my Mother can live on through her baking.

I took this opportunity to take the kiddos to Hoffman Farms Store, a local you-pick fruit stand so they could experience picking your own plump berries, just like I did when I was a kid. Avalon and Ezra really got into it and we had a ton of fun!

The thing I love about this recipe is that it’s incredibly easy to make and you can switch out the berries for any kind of fruit that is in season! Strawberries, rhubarb, peaches, blueberries, raspberries, apples… the list goes on and on. You can even switch out the white sugar for brown sugar and add in some different spices depending on the fruit that you’re using.

If you’re lucky enough to live in Oregon, you can even use Marionberries which are like blackberries but about 3 times as big! Just look at this comparison!

Blackberry Sponge Cake FAQ

Can I use other kinds of fruit?

Yes you can! Any berry or fruit that you like can be used in place of blackberries.

Can this be made ahead?

I don’t recommend making this ahead of time, it tastes the best warm out of the oven but it can be re-heated if you have leftovers. Store leftovers in the fridge because of the fresh fruit.

Can this be made into a layer cake?

I don’t recommend it but it could be made into an upside-down cake by baking it into a cake pan and then flipping it out onto a platter before serving.
